This was tested in people. That is the most reliable kind of research we share.
This was seen in past patients, but it is not yet tested as a way to choose treatment.
The short version
One MRI reading, taken before treatment, was linked to how long bevacizumab: A drug that acts on the blood vessels a tumor builds. In brain tumors it is used mainly to control symptoms from swelling, and to reduce how much steroid someone needs. See the glossary held the tumor back.
What was studied. Researchers looked back at sixty people at one hospital whose glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary had come back. All had an IDH gene change: A small change in a tumor's IDH gene. It is the first thing your team looks at when naming an adult glioma, and it can affect which treatments are offered. Your pathology report says whether your tumor has it. See the glossary, got the drug bevacizumab: A drug that acts on the blood vessels a tumor builds. In brain tumors it is used mainly to control symptoms from swelling, and to reduce how much steroid someone needs. See the glossary, and had a special MRI scan before treatment.
What they found. People with a higher reading on this scan went longer before the tumor grew again. The typical time was 5.46 months, compared with 2.76 months for those with a lower reading. The reading did not show who would live longer overall.
What this means, and what it doesn't
What it could mean: Someday, this MRI reading might help doctors see who is more likely to be helped by bevacizumab: A drug that acts on the blood vessels a tumor builds. In brain tumors it is used mainly to control symptoms from swelling, and to reduce how much steroid someone needs. See the glossary. That could help patients and doctors choose a treatment.
What it doesn't mean: This does not mean the scan is ready to guide treatment choices today. The study looked back at past records from one hospital, so it must be tested in new patients first. A higher reading was not linked to living longer. This is not a cure, and bevacizumab: A drug that acts on the blood vessels a tumor builds. In brain tumors it is used mainly to control symptoms from swelling, and to reduce how much steroid someone needs. See the glossary is not a cure.
